Abstract
A ground engaging tool locking system includes a pin having a first, proximal head region and a second, distal end region spaced from the first, proximal head region along an axis. The pin includes a groove located between the first, proximal head region and the second, distal end region. A biasing element is disposed at least partially within the groove.
Claims20
A ground engaging tool locking system comprising:
- a pin having a first, proximal head region and a second, distal end region spaced from the first, proximal head region along an axis, wherein the pin includes a groove located between the first, proximal head region and the second, distal end region, wherein the pin further includes a tool engagement recess at the proximal head region that extends axially toward the distal end region along the axis and is sized and shaped to receive a tool to rotate the pin about the axis;
- and
- a biasing element disposed at least partially within the groove.
A ground engaging tool locking system comprising:
- a pin having a first, proximal head region and a second, distal end region spaced from the first, proximal head region along an axis, wherein the pin includes a groove located between the first, proximal head region and the second, distal end region, wherein the groove is configured to receive a biasing element, and wherein the pin includes separately spaced helical ramped surfaces along a distal end of the first, proximal head region.
A ground engaging tool locking system comprising:
- an adapter configured to be coupled to a lip of a dipper on a mining machine, the adapter having an interior passage to receive a pin, wherein the interior passage includes a first diameter where a distal end region of the pin is configured to initially enter the adapter, and a second diameter that is disposed further within the adapter, wherein the second diameter is smaller than the first diameter, and wherein the adapter includes separately spaced helical ramped surfaces configured to contact corresponding separate helical ramped surfaces on the pin.
